### 1/5 — Adjusting times

*2025-12-11*

Can’t adjust times to add items at precise times. Only takes it as it’s entered, no editing enabled.

### 5/5 — Awesome!

*2025-11-14*

Is it ClearBAC or BetterBAC? that’s what it says on the Home Screen. Either way, great app! Wondering if you could do a version for other things as well…;)

### 1/5 — You cannot adjust how many ounces you drink!

*2025-04-24*

You cannot set the amount of alcohol. You cannot put in your height. You cannot add more drinks and there is only three. Please make more options. I would be afraid to trust this app!

### 4/5 — Functional

*2025-03-27*

I really like the app and it works as I expected.

However, I’d appreciate an IAP to remove the banner ads. Also, I’d like to be able to connect to Apple Health to automatically add drinks to my health data.

### 5/5 — The only good one

*2025-02-08*

This is the only app in the App Store that tracks BAC in a clear and usable way. Don't bother with the others, I tried like 7 of them before this one came out and they were all junk.

**Developer response:** Thanks!
